Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.
RFID is a better technology than bar codes in many ways. The two are different technologies and have different applications, which sometimes overlap. The big difference between the two is bar codes are line-of-sight technology. That is, a scanner has to "see" the bar code to read it, which means people usually have to orient the bar code towards a scanner for it to be read. Radio frequency identification, by contrast, doesn't require line of sight. RFID tags can be read as long as they are within range of a reader. Bar codes have other shortcomings as well. If a label is ripped, soiled or falls off, there is no way to scan the item. And standard bar codes identify only the manufacturer and product, not the unique item. The bar code on one milk carton is the same as ever...

- RFID stands for Radio Frequency Identification. RFID is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object (Wikipedia.com, 2012). RFID is a type of identification system devices that stored data, identification or location of the products. The RFID tag can be put onto an object and used to track and manage inventory, assets, people, etc. For example, it can be put into cars, computer equipment, books, mobile phones, etc....

- Radio Frequency Identification Introduction RFID is an acronym for Radio Frequency Identification. It is an automatic identification technique that helps to identify and track the objects, people or animals through radio frequency waves. This technology enables wireless data communications. Data storing and retrieving is done through electromagnetic transmission to an RF compatible integrated circuit. It provides a link to data without the need to make physical contact with the object and does not require line of sight communication.... [tags: Technology]

- Introduction RFID is an acronym of Radio Frequency Identification. RFID systems allow for contactless identification of objects. An RFID system is made up of three parts – the RFID tag itself (also called a transponder), a device which reads the tag and a (backend) IT system which looks up the ID on the tag with a database record to identify and describe the object. The RFID tag consists of a silicon chip, containing a unique identification number and an antenna which communicates with the reader device.... [tags: RFID, Transponder, Tag, Backend, Radio]

- Introduction Overview of Automatic Identification techniques used in SCM Automatic identification is a technique which is used as an identification method for keeping appropriate stock units in the supply chain management, uses technologies such as RFID, barcodes etc. (Automatic Identification and Its Role in Warehouse Management, 2013). Automatic identification is a process of automatically recognizing the items, gathering the information about them, and entering that information right into computers without human intervention (What is Auto-ID, 2013)....

- RADIO FREQUENCY IDENTIFICATION Introduction RFID is a technology which enables detecting and identifying objects using electromagnetic radio waves. This is processed through exchange of information between a reader and a tag being attached to the object that includes the data associated with the object. This can be used to detect and classify vehicles, animals, patients, shipment goods and airline baggage.  RFID technology involves two main components, they are transponders which are also known as tags or labels, contain the relevant information about the object and other the interrogators, also known as readers or transceivers, that extract the data from the tags....

- Purpose of Report The purpose of this report is to outline the benefits that an investment in wearable identification tags could bring to the business. This organisation is very human resource intensive and this technology will save resources in this department which will directly benefit the business. Assumptions In preparing this business case, I have made several assumptions regarding the implementation of this technology: • As this is an international company, each separate office has a HR presence and processes time-sheeting locally....

- Topic: Radio Frequency Identification (RFID) . Radio Frequency Identification (RFID, is a automatic identification technology that uses electromagnetic or electrostatic coupling in the radio frequency to identify an object, animal or person. RFID consists of three components: a scanning antenna, a transceiver with decoder and a transponder. The antenna contained in the RFID tag transmits a signal that activates a transponder through radio frequency waves. The RFID tag or transponder transmits the data back to the antenna providing information such as product identification, location status or pricing.... [tags: technology, 500 KHz, electromagnetics]

- Radio frequency identification (RFID) is a computerized ID innovation that uses radio recurrence waves to exchange information between an onlooker and things that have RFID gadgets, or tags, joined. The tags hold a microchip and receiving wire, and work at universally distinguished standard frequencies. Barcodes are much smaller, lighter and easier than RFID but RFID offers significant advantages. One major advantage of RFID is that the innovation doesn't oblige any observable pathway the tags could be perused as long as they are inside the range of the spectator, whereas in barcodes in order to read the barcode the barcode scanner should close around 10-15 fts....
